Abstract:
One example method includes exposing a block storage which is distributed across a group of multiple sites, receiving a primary write request that identifies data to be stored, separating data identified in the primary write request into multiple data pieces, encoding the data pieces by creating multiple new blocks of data based on the multiple data pieces, where the data pieces are encoded in such a way that when a sufficient number, but fewer than all, of the multiple new blocks of data are retrieved, the data identified in the write request is recoverable by decoding, and writing the new blocks of data to different respective sites of the group, where writing of the new blocks of data is performed in conjunction with a plurality of secondary write requests, each of which corresponds to one of the new blocks of data.
